What is the Origin of Sub-Clinical Insufficiency?

This concept is a cornerstone of functional endocrinology, developed to account for patient symptoms that standard diagnostic criteria fail to explain. Its origin lies in recognizing that an individual requires a higher concentration of a signaling molecule to achieve robust feedback and optimal cellular response than the population average suggests.

What is the Mechanism of Sub-Clinical Insufficiency?

The mechanism involves the system requiring higher levels of a substance to overcome mild receptor resistance or increased clearance rates inherent to the individual's physiology. Consequently, while the level is not pathologically low, it is insufficient to drive the necessary downstream signaling cascade for maximal vitality and homeostasis.

Sub-Clinical Insufficiency

Meaning

Sub-Clinical Insufficiency describes a physiological state where the concentration of a critical hormone or metabolite falls measurably below the established optimal functional threshold, yet remains technically within the broad reference range provided by standard laboratory testing. This condition represents a functional deficit impacting subjective well-being and performance, even without overt pathology. We address this gap between statistical normality and peak physiological function.
